Heh, I just saw the big welcome sign for BofA US customers when signing into my Barclaycard. This is interesting because w/ the merger, Barclay is the next on the list of banks to be ousted by AA, so I'm wondering when AA will stop selling points to Barclay and you'll get tossed around again.
This is a rather interesting conversion, I wonder how it'll reflect on credit reports (open dates, whether it's a new trade line, etc).
For the BofA loyalists, this is a blow, but I've found my short stay so far at Barclaycard to be pretty good. They were quick to match signup offers that they increased after I signed up myself, and free FICO scores is always appreciated as well. Their website is a little archaic, but functional.
